The Tec System is very unique. Ive never seen anything like it to be honest. Well nothing in that size.

Nice work. Cant wait to hear your update with the Higher currant on the TEC. This should also give you a boost in power.

Man I really like that alot how it separate and you can pre chill.

On my set up i have a delay start on the diode. There is no other way to do it in my host but i wish i could do something like you did. Side clicky would be the best choose for this i think because you can add the key.

Over all nice build. +3
Glad you like it Angelos!

I sent PayPal for that 1.3 Amp X-Drive buck driver...

These are great drivers!

Default Re: 445 Mag Mod with TEC...

(tried to just edit my last post, but was blocked and could not for some reason??)

Update:

I did some testing, and found that the peltier is getting enough current, but needs more heatsinking mass for the hot side...

I did not have much room inside, but made the largest heatsink that I could fit without interfering with the air flow.

I couldn't go much deeper (thicker), so I went a little wider.



I know... It isn't pretty.

But it works a little better now. Still not as good as my Ice Box builds. But for the size of the peltier, and this 'hot' of a diode, it does ok.

Fun project anyway...

P.S. Don't even think I still don't want that driver Angelos! I'll use that bad boy for something else. I like these X-Drive buck drivers...

Looks clean to me... one question jay I see how you used the X-drive to run the diode of course, but could you use a seperate buck drive to run the TEC and fan in parallel. You could shoot for the current needed by the peltier in this case 1.6A as you stated and after that I assume the fan would spin up pretty good givin the >8V that the batteries are putting out?

What I was trying to ask was if one was to use another driver instead of the homemade regulator you have for the TEC/fan assembly could that be another way to skin the cat?

Yes absolutely!

I have two drivers in my Ice Box builds. In those, I can adjust the current/cooling going to the peltier...

In both cases, I am running the fan direct off of the 5 volt supply. (7805)

But yes you can use another driver dedicated to the peltier if you wanted to...

Thanks jay, if you personally don't mind I'm going to use a mag light also. I can't seem to find a host that has that big of a cavity to do such a thing.

I did some testing with a Melcore CP1.0-127. It's max values are 15.V max and 2.6A draw max. I benched it using a sunan 40mm fan that I plan on using for my build.

I mounted the hot side on a computer PSU cooler that I double as a driver cooler while bench settings something like this.




I played around with hooking it in series with the fan without the fan and so forth.

Heres what worked best for me.

The peltier I hooked up to a driver that was rated for 8.4V max input and set to run at 1.8A. The peltier was drawing so much current that the driver would only be able to deliver 1.6A at the 8.4V input. I pushed it up to 10V only for a couple seconds as I have done testing these cheap drivers in the past and achieved 1.8A.

I think I'll use this driver anyway it's the buck driver powerbuck from lazerer. It seems to be a good choice for now because the peltier seems to prefer the 1.6A at 8.4V before the dreaded condensation factor comes into play.

That is all I have for now, once I get the total TEC package assembled I will give more acurate #'s put into stone.

I don't mean to jack this thread, but I did not want to take away from an allready awsome thread about the same suject, TEC maglights, who knows? maybe it will generate a buyer or two to one of jay most worthy builds
